A mocked-up jokey text exchange between Prince Harry and Jon Bon Jovi has been shared by the Sussex Royal Twitter account.

In the video the royal tells the musician he is “livin’ on a prayer” as they arrange to meet in London.

The pair will meet at a music studio when the musician records a single in aid of the Invictus Games Foundation, which supports an international multi-sport event for injured or sick military personnel.
